The relationship between the grid and the flat panel detector

As a key component of X-ray imaging diagnostic system, wire grid plays a decisive role in removing scattered rays and increasing image contrast. The combination of grid and flat panel detector plays an important role in the effect of artifact removal.
The combination of the flat panel detector and the grid includes: collecting the exposed first image; acquiring basic information of the flat panel detector; acquiring the theoretical frequency of the grid lines of the grid; The actual sampling frequency is calculated according to the theoretical frequency of the grid line and the actual sampling frequency of the flat panel detector to calculate the estimated frequency of the grid line artifacts in the first image caused by the grid; the estimated frequency of the grid line artifacts is the center Setting a maximum allowable deviation interval; and searching for the actual frequency where the grid line artifact is located within the maximum allowable deviation interval, and removing the grid line artifact in the first image to obtain a second image.
After reading this, you all know the relationship between the grid and the flat panel detector, right?
